Gantry type with movable portal and crossbeam

PRG-W gantry type portal milling and turning center with height-adjustable crossbeam for maximum precision and flexibility for machining large, complex and high-precision workpieces with extremely large dimensions. An extremely heavy cast metal design with optimum damping properties and the INA linear guiding system equipped with hydro mechanical damping slides as the basis for the ultra-modern PMG-W portal turning and milling centers. Freely selectable lengthwise travel for flexible multi-station machining at all times. Optional multitasking for machining high-precision prismatic and cubic workpieces in one set-up replaces vertical turning and drilling machines.
